Mist and lingering fog threatens to mar revellers' enjoyment of tomorrow night's New Year's Eve firework displays, forecasters said.
The bitterly cold weather has given way to a welcome rise in temperatures. However, warmer air has reacted with the cold ground, throwing a haze of fog across much of the country this week.
Experts predict this murky blanket shows no sign of easing. The Met Office forecaster Mark Seltzer said: "Fog combined with the low-lying cloud is going to prove problematic for fireworks displays."
